TemporalSmoother Settings

[FreierGeist]

hi
i'd like to know if there's a less "blurrier" setting to SmartSmoother (Little Noise) than the default one (2,1)
i know that the first number its the "strenght" and the second is the treshold
but looks like (1,1) disable the filter...
please, someone enlighten me about this filter and its settings

thanks!!!

If you are talking about my VirtualDub Smart Smoother filter imported to Avisynth, then you are totally off the wall. It takes 3 parameters:

SmartSmoother(diameter,threshold,interlaced)

diameter can be 3, 5, 7, 9, or 11. threshold goes from 1 to 255. interlaced is 0 for progressive source and 1 for interlaced source.

Thus, your SmartSmoother(2,1) is illegal and will yield undefined results.

If you really did mean Temporal Smoother as in your subject line, then why are you talking about Smart Smoother? Just trying to confuse everybody?

Hi-

Yeah-he's talking about the Temporal Smoother. The "Little Noise" reference is the giveaway that only a GKnot user would know. He just misspoke himself, as they say.

AUEhUAHeUAHE
sorry :)
i meant the Temporal Smoother :)
the questions are about the Temporal Smoother
manono's right about the GKnot's "Little Noise" refference :)
at first this thread was posted at "Gordian Knot" section
then some moderator has moved it to here
:)

thanks
and sorry about the mistakes

For TemporalSmoother, the first parameter is the strength (0-10); the second is the temporal radius. Strength is an integer.

[Dali Lama]

Well, most people use a threshold of 3 so it would be:

TemporalSmoother(3)

The default in Gknot is:

TemporalSmoother(2,1)


I suppose that TemporalSmoother(3) uses a one as its radius too, but its not put in, beause its set by default at one.

Make sure if you apply this filter, especially the "3" one to apply it "before" resizing, as it blurs the image less and you still manage to get rid of any small noise/detail.

later,

Dali

hmmmm
ok
thanks
is the TemporalSmoother(3) "blurrier" than TemporalSmoother(2,1) ???

and what does the temporal radius do as well?

Default radius is 3, not 1. 3 is the value used in the virtualdub filter. It means that seven frames will be examined, for each frame to process (the current frame, 3 before and 3 after).

Temporal Smoother shouldn't blur, but can produce ghosting artifacts if the strength is set too high. With a strength of 2 it shouldn't happen very often.

Increasing the radius somewhat increases the effectiveness of the filter without causing artifacts, but costs more processing power.

Best values are of course source specific, (2,1) is rather conservative in most case.

mmm..


for me temporalsoften looks far more superior as it can filter that bloody luma noise and leave the picture perfect (separate luma and chroma threshs).

the downside is, it has lame errors (drops if no trimming) and is terribly slooooow.
